@PECIFICATION forming part of Letters Patent No. 297,403, dated April 22, 1884.

Application [iled February 29, 1884.

To all whom it may concern.-

Be it known that I, JOHN WV. HUDSON, a citizen of the'United States, residing at Vellington, in the county of Iroquois and State of Illinois, have invented certain new and useful Improvements in food-Shaping lllachines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

My invention relates to a machine for finishing irregular forms, designed as an improvement upon thel device patented to me December 5, 1882, and numbered 268,405, and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims.

` In the device above mentioned a table was provided with cam-slots, in which slots operated revolving cutter-heads which had'verti-.

cal play and such lateral play as the canislots compelled. The blank to be operated upon was secured upon the table, and as the table moved in one direction the cutters and finishers gave the desired form to the blank. rIhe table had then to be moved idly back in order to treat another blank.

In the present invention I form an endless table in sections, and lso arrange the earn-slots that the blanks may be placed in position and operated upon continu ously, the finished articles being 'deposited at one end of the machine as soon as finished.

The invention consists, essentially, in the construction and arrangement of this endless table in oval boxes which traverse the camslots, and in which the spindles of the cutterheads revolve, and in other features of construction, arrangement, and adaptation, all as will be more fully hereinafter set forth.

For convenience 'I will only illustrate and describe in this specication such parts as are necessary to a full understanding of novel features claimed, the details of other points being sufficiently covered in the patent hereinbefore referred to.

The invention is illustrated in the accompanying drawings, which form a part of this (No model.)

specification, and in which Figure l is aside elevation of a machine embodying my improvements. Fig. 2 is a top plan view thereof. Fig. 3 is a transverse section on the line x x of Fig. 2. Fig. 4t is a vertical section on the line y y of Fig. 3. Fig. 5 is an enlarged View of a portion of the table, showing the oval boxes and their relation to the cam slots. Fig. 6 is a detail view of a portionof the table, showing its, relation to the fan-shaped sprocket-wheels. Fig. 7 is a detail view of a portion of one of the sections of which the table is composed.

Referring to the drawings, in which like letters of reference denote like parts in all the figures, A designates the frame, in which is journaled the power-shaft B, having proper connections, B", with a suitable power, (not, shown,) and carrying also a double pulley, C, one portion of which is belted to a pulley, d, on a shaft, D, of a fau-wheel, E, and the other to a pulley, d, upon the shaft D of the fanwheel E. rIhese'fan-wheels E and E are located at the forward and rear en'ds of the frame, respectively, and their shafts carry pulleys d2 and cl3, which connect by belts with the shafts DAZ D of the fan-shaped sprocketwheels E2 FP, located beneath the fan-wheels E and E. These connecting-pulleys are of such corresponding size as to impel all the fan-shaped sprocket-wheels E E EZ Ff in the same direction with the same speed, the purpose of which will be presently set forth.

Upon the inner surface of the upper rails of the frame A are 'il-shaped projections f,which serve as guides in a groove, f, formed in the ends of the sections F o f the endless table. These sectionsare loosely hinged together, and each section is of a width corresponding to the reach between the arms e of the fan-'- shaped sprocket-wheels, over which the endless table is carried. As the table passes either fan-wheel, it necessarily makes a short bend at its hinge, and the arms e, acting upon the angle thus formed, serves to propel the table in the manner of a chain and sprocket. The upper surface of the endless table is provided with a series of cam-slots, G, and grooves H, for clamping the blank, these clamps H being of any approved construction and arranged in such manner that they shall be equidistant from each other. The cutter-spindles in their IOO arrangement and functions are similar to those of the patent hereinbefore mentioned, and opcrate in boxes K, having an upper iiange, k, which rests upon or traverses the upper edge of the cam-slots, and flange k, which serves similarly upon the lower surfaces ofthe table, the shank or body traversing the slot. rIhis shank is made oval, or in the form of an ellipse in cross-section, which form is peculiarly adapted to its servicein t-he cam-slots.

In order to keep up a proper tension upon the table, and to insure its proper register ot aet-ion by the arms c of the fan-shaped sprocketwheels, the shafts D D, Src., of those wheels are journaled in movable boxes M, and these boxes M may be adjusted outwardly, by means of threaded rods M and nuts m, the rods being rigid with the boxes and extending through the pockets BIZ, as shown in Fig. 2. The iinishing operation is only being accomplished when the upper horizontal portion of the endless table is passing in proximity to the cutters. To insure a proper bearing at such times upon the work, I arrange a series of carrying-rolls, N, journaled in the upper side rails of the frame, and these rolls support the table when it is passing upon its upper horizontal path. Above the table, in movable boxes O, are journaled pressure-rolls P, which serve to hold the work or blank firmly in position until the shaping` is nished. These boxes O operate in frames O', and may be adjusted up or down by rod 0 and nut o', to give more or less pressure upon the work from the springs Q, as may be required. These pressure-rollers I are arranged, preferably, two upon either side of the cutters and one between the rough cutter of each set. Vhen, in the progress of the table, a clamping-place, II, appears, a blank is put in position, and it immediately passes under the pressure rolls P and is properly shaped by the cutters. As soon as the table passes over the wheel E, the iinished article is released and is deposited at the end of the machine.

As in the patent cited, the invention is especially adapted to the formation of hames, and the cam-slots may be readily arranged to have the blanks iinished rights and lefts, to iit either side of the collar.

The operation ofthe spindles and cutters in their vertical and lateral movements is the same as in the patent cited, and forms no part of this invention. Modifications in details of construction may be made without departing from the principle or sacrificing the advantages of my invention, the essential features of which will be readily understood from the foregoing description, taken in connection with the accompanying drawings.

Vhat I claim as my invention, and desire to secure by Letters Patent of the United States,
